Italian music publisher Diabelli made a competion and invited composers to write variations to his 32 bar waltz. Many famous composers participated, Beethoven called everyone a retard and the theme stupid and worthless. Then locked himself in and spent 1 year composing 33 variations to this, most of which are mocking other composers' styles. What a troll
Nas' The Lost Tapes 2 is another case of a legendary rapper who hasn't lost his lyrical ability but just doesn't have the fire anymore. Possibly the most forgettable of all his albums imo.
